COMPOSITION CONTAINING BRANCHED POLYMER FOR VIBRATION-DAMPING MATERIAL |
摘要 |
<p>An object of the present invention is to provide a damping material which exhibits a very high vibration-damping (energy-attenuating) performance against vibrations in a low frequency range (several hertz) or a higher frequency range in a specific temperature range near room temperature (20 to 20°C), which can be controlled in vibration-damping performance at will to target performances not only in a low-temperature and high-frequency range but also in a very low specific frequency range and a specific temperature range, and which can be designed with a high flexibility. The object is attained by a composition for damping material including a branched polymer (A), and a resin (B), wherein the content by percentage of the branched polymer (A) is from 15 to 85% both inclusive by weight for 100% by weight of the total of the branched polymer (A) and resin (B).</p> |
